HEATING RECUMBENT CABINET Filed June 19, 1953 INVENTOR ATTORNEY \M X XUnited States Patent HEATING RECUMBENT CABINET Waldemar Hakonsson,Copenhagen, Denmark Application June 19, 1953, Serial No. 362,698

1 Claim. (Cl. 128-373) The present invention relates to an improvedheating recumbent cabinet for medical purposes.

Heating cabinets are already known in which the patient is placed insuch a position that his body is subjected to the efiect partly ofmedical rays and partly of heating rays issuing from light and thermalapplicators respectively arranged within the cabinet. The patient lieson a couch in relation to which the applicators are placed partly aboveand partly below the patient on the couch. An essential drawback inconnection with these hitherto known heating cabinets is that it is onlypossible at a considerable expense to arrange the cabinet in such amanner that the patient is not subjected to injurious effects due to thesaid radiations.

According to the invention this drawback is eliminated by providing aheating cabinet in which there is arranged above the couch a lightapplicator for certain rays such as for instance infra red rays, andbelow the couch is arranged one or several thermal applicators, whichare screened in relation to the couch by means of a ceramic casingsurrounding the heating elements in order to prevent direct radiation.In this manner is attained that the couch need not be made of expensivematerial otherwise necessary to prevent direct penetration of heat raysfrom the thermal applicators beneath the couch.

The invention is characterized by other features as will be evident fromthe following description taken in conjunction with the accompanyingdrawing, in which Fig. 1 is a side elevation of a heating cabinetaccording to the invention, and

Fig. 2 shows on an enlarged scale an exploded side elevation of athermal applicator as used in the heating cabinet.

The heating cabinet illustrated in Fig. 1 comprises an "ice elongatedcasing 1 provided with legs 2. Inside the casing 1 is arranged a couch 4raised somewhat above the base 3 of the casing 1, and by means of whichthe patient may take up a recumbent position in the casing. In the upperwall of the casing there is an electrical light applicator 5 forproducing for instance infra red rays, the applicator being so arrangedthat it may issue rays to any part of a patient lying on the couch.Beneath the couch 4 inside the casing there is arranged one or severalelectrical thermal applicators 6 which, or all of which is/are insertedin series with the light applicator 5, the electrical wiring beingindicated by 7. Further, the electrical circuit includes a controllingclock 8 for regulating the time of operation of the light applicator 5and the thermal applicators 6.

In Fig. 2 a thermal applicator 6 is shown. This applicator consists of aheating filament 9 which is carried through a tube 10 made of a ceramicsubstance such as e. g. chamotte. At each end this tube 10 is carried bya frame 11 so shaped that the tube is somewhat raised from the casingbase 3. The frame 11 is provided with terminals 12 for interconnectingthe ends of the filaments 9 and the wires 7. Preferably the exterior ofthe ceramic tube 10 is provided with projections, e. g. as shown ahelical thread 13 in order to increase the heat radiation.

I declare that what I claim is:

A heating cabinet for medical purposes including a casing, a couchwithin the casing spaced from the base thereof, at least one lightapplicator arranged above the couch, at least one heating elementarranged between the couch and the cabinet base, means for connectingthe said light applicator and heating element to an electric circuit,and a screen interposed between the couch and the heating element, inwhich the screen comprises a tube made of a ceramic material surroundingthe heating element.
